Because it can be much simpler, in the form

;; field is 'from or 'message-id for instance
(eval (format "mail-header-%s" (symbol-name field)))

Only a few lines, and it could be used with anything as the field,
instead of the hard-coded field names I have now.  It also seemed
like an interesting challenge, but I failed it pretty badly :)

That's what I figured, too.  Actually I also ran into this while
updating spam-check-BBDB and ended up including the expanded macro
calls that look up a name or address in the BBDB hashtable inside
spam.el.
